If there's couple thousand meters of height,

and volume within this height,

 

length, be it 50KM to 100KM,

'thin' wires (as compared to the volume)

can be sustained.

 

Then a bridge, without the usage

of turbines (though if helpful, can be)

 

that is designed to be used with lighter

vehicles (that can float on water)

(and get back up by flight as well)

(and use the narrower space of the commute)

 

is possible.

 

 

So. One could say, this could be.

 

Vehicles designed for intercontinental travel.
